BACKGROUND

A user environment, such as a residence or an office building forexample, may be configured using various types of load control systems.A lighting control system may be used to control the lighting loads inthe user environment. A motorized window treatment control system may beused to control the natural light provided to the user environment. Aheating, ventilation, and air-conditioning (HVAC) system may be used tocontrol the temperature in the user environment. Each load controlsystem may include various control devices, including control-sourcedevices and control-target devices. The control-target devices mayreceive digital messages, which may include load control instructions,for controlling an electrical load from one or more of thecontrol-source devices. The control-target devices may be capable ofdirectly controlling an electrical load. The control-source devices maybe capable of indirectly controlling the electrical load via thecontrol-target device. Examples of control-target devices may includelighting control devices (e.g., a dimmer switch, an electronic switch, aballast, or a light-emitting diode (LED) driver), a motorized windowtreatment, a temperature control device (e.g., a thermostat), an ACplug-in load control device, and/or the like. Examples of control-sourcedevices may include remote control devices, occupancy sensors, daylightsensors, temperature sensors, and/or the like.

SUMMARY

As described herein, a remote control device may be configured to beplaced on a horizontal surface (e.g., such as a tabletop, a desk, acounter, etc.). The remote control device may include a base and arotating portion. The rotating portion may rotate with respect to thebase. The remote control device may be configured to control a loadcontrol device of a load control system for controlling an amount ofpower delivered to an electrical load (e.g., to control an intensity ofa lighting load). As the rotating portion is rotated, the remote controldevice may cause the load control device to adjust the amount of powerdelivered to the electrical load.

The base may be configured to be attached to a pedestal. The pedestalmay include a top plate and a bottom plate. The bottom plate may beconfigured to rest on the horizontal surface. The bottom plate mayinclude a concave bottom surface. The concave bottom surface may includea recessed portion and a flat portion. The flat portion may be along anouter perimeter of the bottom plate. The flat portion may be configuredto rest on the horizontal surface. In addition, the pedestal may includea mounting tab that may extend from the top plate (e.g., a platform onthe top plate). The mounting tab may be configured to extend into anopening defined by the base. The mounting tab may be configured toprevent rotation of the base of the remote control device when the baseis attached to the pedestal.

DETAILED DESCRIPTION

FIG. 1 is a simplified block diagram of an example load control system.As shown, the load control system is configured as a lighting controlsystem 100 for control of one or more lighting loads, such as a lightingload 102 that is installed in a ceiling-mounted downlight fixture 103and a controllable lighting load 104 that is installed in a table lamp105. The lighting loads 102, 104 shown in FIG. 1 may include lightsources of different types (e.g., incandescent lamps, fluorescent lamps,and/or LED light sources). The lighting loads may have advancedfeatures. For example, the lighting loads may be controlled to emitlight of varying intensities and/or colors in response to a usercommand.

The lighting control system 100 may include one or more control devicesfor controlling the lighting loads 102, 104 (e.g., controlling an amountof power delivered to the lighting loads). The lighting loads 102, 104may be controlled substantially in unison, or be controlledindividually. For example, the lighting loads may be zoned so that thelighting load 102 may be controlled by a first control device, while thelighting load 104 may be controlled by a second control device. Thecontrol devices may be configured to turn the lighting loads 102, 104 onand off. The control devices may be configured to control the magnitudeof a load current conducted through the lighting loads so as to controlan intensity of the lighting loads 102, 104 between a low-end intensityL_(LE) and a high-end intensity L_(HE), for example.

The control device described herein may be, for example, a dimmer switch110, a retrofit remote control device 112, a wall-mounted control device114, a tabletop remote control device 116, and/or a handheld remotecontrol device 118. The dimmer switch 110 may be configured to bemounted to a standard electrical wallbox (e.g., via a yoke) and becoupled in series electrical connection between a power source (e.g., analternating-current (AC) power source 105 or a direct-current (DC) powersource) and a lighting load that is wired into the control path of thedimmer switch 110 (e.g., such as the lighting load 102). The dimmerswitch 110 may receive an AC mains line voltage V_(AC) from the AC powersource 105, and may generate a control signal for controlling thelighting load 102. The control signal may be generated via variousphase-control techniques (e.g., a forward phase-control dimmingtechnique or a reverse phase-control dimming technique). The dimmerswitch 110 may be configured to receive wireless signals (e.g., from aremote control device) representative of commands to control thelighting load 102 (e.g., the intensity and/or color of the lightingload), and generate respective control signals for executing thecommands. Examples of wall-mounted dimmer switches are described ingreater detail in commonly-assigned U.S. Pat. No. 7,242,150, issued Jul.10, 2007, entitled DIMMER HAVING A POWER SUPPLY MONITORING CIRCUIT; U.S.Pat. No. 7,546,473, issued Jun. 9, 2009, entitled DIMMER HAVING AMICROPROCESSOR-CONTROLLED POWER SUPPLY; and U.S. Pat. No. 8,664,881,issued Mar. 4, 2014, entitled TWO-WIRE DIMMER SWITCH FOR LOW-POWERLOADS, the entire disclosures of which are hereby incorporated byreference.

The retrofit remote control device 112 may be configured to be mountedto a mechanical switch (e.g., a toggle switch 122, a paddle switch, apushbutton switch, a “light switch,” or other suitable switch) that maybe pre-existing in the lighting control system 100. Such a retrofitsolution may provide energy savings and/or advanced control features,for example without requiring significant electrical re-wiring and/orwithout requiring the replacement of existing mechanical switches. As anexample, a consumer may replace an existing lamp with the controllablelighting load 104, switch a toggle switch 122 that is coupled to thelighting load 104 to the on position, install (e.g., mount) the remotecontrol device 112 onto the toggle switch 122, and associate the remotecontrol device 112 with the lighting source 104. The retrofit remotedcontrol 112 may then be used to perform advanced functions that thetoggle switch 122 may be incapable of performing (e.g., such as dimmingthe intensity level of the light output, providing feedback to a user,etc.). As shown, the toggle switch 122 is coupled (e.g., via a serieselectrical connection) between the AC power source 105 and an electricalreceptacle 120 into which the lighting load 104 may be plugged (e.g., asshown in FIG. 1 ). Alternative, the toggle switch 122 may be coupledbetween the AC power source 105 and one or more of the lighting loads102, 104, without the electrical receptacle 120. The retrofit remotecontrol device 112 may be operable to transmit the wireless signals tothe controllable light source 104 for controlling the intensity and/orcolor (e.g., color temperature) of the controllable light source 104.The remote control device 112 may also be configured to transmitwireless signals for control of other electrical loads, such as forexample, the volume of a speaker and/or audio system, the position of amotorized window treatment, the setpoint temperature of a heating and/orcooling system, and/or a controllable characteristic of anotherelectrical load or device.

The wall-mounted remote control device 114 may be configured to bemounted to a standard electrical wallbox and be electrically connectedto the AC power source 105 for receiving power. The wall-mounted remotecontrol device 114 may be configured to receive a user input and maygenerate and transmit a control signal (e.g., control data such as adigital message) for controlling the lighting loads 102, 104 in responseto the user input. The tabletop remote control device 116 may beconfigured to be placed on a surface (e.g., an end table or nightstand), and may be powered by a direct-current (DC) power source (e.g.,a battery or an external DC power supply plugged into an electricaloutlet). The tabletop remote control device 116 may be configured toreceive a user input, and may generate and transmit a signal (e.g., adigital message) for controlling the lighting loads 102, 104 in responseto the user input. The handheld remote control device 118 may be sizedto fit into a user's hand, and may be powered by a direct-current (DC)power source (e.g., a battery or an external DC power supply pluggedinto an electrical outlet). The handheld remote control device 118 maybe configured to receive a user input, and may generate and transmit asignal (e.g., a digital message) for controlling the lighting loads 102,104 in response to the user input. Examples of battery-powered remotecontrols are described in greater detail in commonly assigned U.S. Pat.No. 8,330,638, issued Dec. 11, 2012, entitled WIRELESS BATTERY POWEREDREMOTE CONTROL HAVING MULTIPLE MOUNTING MEANS, the entire disclosure ofwhich is hereby incorporated by reference.

The control devices described herein (e.g., the dimmer switch 110 and/orremote control devices 112-118) may each include one or more lightsources (e.g., LEDs) configured to be illuminated to provide feedback toa user of the control device. Such feedback may indicate, for example, astatus of the lighting loads 102, 104 such as whether the lighting loadsare on or off, a present intensity of the lighting loads, and so on. Thefeedback may indicate a status of the control device itself such as apower status of the control device (e.g., remaining battery power). Thefeedback may indicate to the user that the control device istransmitting control signals (e.g., RF signals) in response to anactuation of the control device. The control device may be configured tokeep the one or more light sources illuminated while the conditiontriggering the feedback continues to exist. The control device may beconfigured to illuminate the one or more light sources for a few seconds(e.g., 1-2 seconds) and then turn off the light sources (e.g., toconserve battery life).

The control devices may be configured to be dim (e.g., not illuminated)the one or more light sources so that no feedback is provided when thecontrol devices are in an idle state. The control devices may thenilluminate the one or more light sources to provide the feedback inresponse to detecting a user within close proximity of the controldevices. Such detection may be based on, for example, a finger hoveringnear a front surface of the control devices. The presence of the usermay be detected, for example, via a capacitive touch element or anelectrical field sensor comprised in the control devices.

The control devices may each include a control circuit. The controlcircuit may be configured to be responsive to a user input and generatecontrol data (e.g., a control signal) for controlling the lighting loads102, 104 based on the user input. The control data may include commandsand/or other information (e.g., such as identification information) forcontrolling the lighting loads 102, 104. The control circuit may beconfigured to illuminate the one or more light sources to provide thefeedback described herein.

One or more of the control devices may include a wireless communicationcircuit (e.g., a radio frequency (RF) transmitter) operable to transmitand/or receive wireless signals such as RF signals 108. The wirelesssignal may be used to transmit control data (e.g., a digital message)generated by the control devices to the lighting loads 102, 104 or to acentral controller of the lighting control system 100, for example. Thelighting loads 102, 104 may be associated with a control device during aconfiguration procedure such that the lighting loads 102, 104 may beresponsive to control signals transmitted by the control device. Toillustrate, the association may be accomplished by actuating an actuatoron the concerned lighting loads, and then actuating (e.g., pressing andholding) an actuator on the control device for a predetermined amount oftime (e.g., approximately 10 seconds). Examples of a configurationprocedure for associating a control device with an electrical load isdescribed in greater detail in commonly-assigned U.S. Patent PublicationNo. 2008/0111491, published May 15, 2008, entitled RADIO-FREQUENCYLIGHTING CONTROL SYSTEM, the entire disclosure of which is herebyincorporated by reference.

The control devices may each include a memory. The memory may be used,for example, to store operational settings associated with the controldevice and/or the lighting loads 102, 104. The memory may be implementedas an external integrated circuit (IC) or as an internal circuit (e.g.,as part of a control circuit).

The load control system 100 may include one or more of a remoteoccupancy sensor or a remote vacancy sensor (not shown) for detectingoccupancy and/or vacancy conditions in a space surrounding the sensors.The occupancy or vacancy sensors may be configured to transmit digitalmessages to the lighting loads 102, 104 (e.g., via the RF signals 108)in response to detecting occupancy or vacancy conditions. Examples of RFload control systems having occupancy and vacancy sensors are describedin greater detail in commonly-assigned U.S. Pat. No. 8,009,042, issuedAug. 30, 2011, entitled RADIO FREQUENCY LIGHTING CONTROL SYSTEM WITHOCCUPANCY SENSING, the entire disclosure of which is hereby incorporatedby reference.

The load control system 100 may include a remote daylight sensor (notshown) for measuring a total light intensity in the space around thedaylight sensor. The daylight sensor may be configured to transmitdigital messages, such as a measured light intensity, to the lightingloads 102, 104 such that the lighting loads may be operable to adjusttheir respective intensities in response to the measured lightintensity. Examples of RF load control systems having daylight sensorsare described in greater detail in commonly assigned U.S. Pat. No.8,451,166, issued May 28, 2013, entitled WIRELESS BATTERY-POWEREDDAYLIGHT SENSOR, the entire disclosure of which is hereby incorporatedby reference.

The load control system 100 may include other types of input devices,for example, radiometers, cloudy-day sensors, temperature sensors,humidity sensors, pressure sensors, smoke detectors, carbon monoxidedetectors, air-quality sensors, security sensors, proximity sensors,fixture sensors, partition sensors, keypads, kinetic or solar-poweredremote controls, key fobs, cell phones, smart phones, tablets, personaldigital assistants, personal computers, laptops, time clocks,audio-visual controls, safety devices, power monitoring devices (such aspower meters, energy meters, utility submeters, utility rate meters),central control transmitters, residential, commercial, or industrialcontrollers, or any combination of these input devices.

It should be further appreciated that although FIG. 1 depicts a loadcontrol system with two lighting loads, the system may include morelighting loads, other types of lighting loads, and/or other types ofelectrical loads. For example, the load control system may include oneor more of the following: a dimming ballast for driving a gas-dischargelamp; an LED driver for driving an LED light source; a dimming circuitfor controlling the intensity of a lighting load; a screw-in luminaireincluding a dimmer circuit and an incandescent or halogen lamp; ascrew-in luminaire including a ballast and a compact fluorescent lamp; ascrew-in luminaire including an LED driver and an LED light source; anelectronic switch, controllable circuit breaker, or other switchingdevice for turning an appliance on and off; a plug-in load controldevice, controllable electrical receptacle, or controllable power stripfor controlling one or more plug-in loads; a motor control unit forcontrolling a motor load, such as a ceiling fan or an exhaust fan; adrive unit for controlling a motorized window treatment or a projectionscreen; one or more motorized interior and/or exterior shutters; athermostat for a heating and/or cooling system; a temperature controldevice for controlling a setpoint temperature of a heating, ventilation,and air-conditioning (HVAC) system; an air conditioner; a compressor; anelectric baseboard heater controller; a controllable damper; a variableair volume controller; a fresh air intake controller; a ventilationcontroller; one or more hydraulic valves for use in radiators andradiant heating system; a humidity control unit; a humidifier; adehumidifier; a water heater; a boiler controller; a pool pump; arefrigerator; a freezer; a television and/or computer monitor; a videocamera; a volume control; an audio system or amplifier; an elevator; apower supply; a generator; an electric charger, such as an electricvehicle charger; an alternative energy controller; and/or the like.

FIGS. 2-5 illustrate an example remote control device 200 attached to apedestal 230. The remote control device 200 may be deployed as thetabletop remote control device 116 in the load control system 100 (e.g.,as shown in FIG. 1 ). The remote control device 200 may be configured tocontrol the amount of power delivered to, and thus the intensity of, atleast one lighting load. The remote control device 200 may include abase 210 and a control unit 220 that may be attached to the base 210.The base 210 may alternatively be referred to as a base portion or amounting assembly. The control unit 220 may alternatively be referred toas a control module. It should be appreciated that other control unitsdescribed herein may similarly be alternatively referred to as controlmodules. The control unit 220 may include a rotating portion that isrotatable with respect to the base 210. For example, as shown, thecontrol unit 220 includes an annular rotating portion 222 that isconfigured to rotate about the base 210. The control unit 220 mayinclude an actuation portion 224, which may be operated separately fromor in concert with the rotating portion 222. The remote control device200 may be configured such that the control unit 220 and the base 210are removably attachable to one another. FIG. 4 depicts the remotecontrol device 200 with the control unit 220 detached from the base 210.

The base 210 may define an opening 212 that extends therethrough andthat is configured to receive at least a portion of the pedestal 230.The base 210 may define a rear surface 214.

The pedestal 230 may be a mount that is configured to rest on ahorizontal surface. The pedestal 230 may be configured to receive theremote control device 200. For example, the remote control device 200may be mounted to the pedestal 230. The pedestal 230 may include a plate240, a platform 250, and a mounting tab 260. The plate 240 may beconfigured to rest on a horizontal surface. For example, the plate 240may define a rear surface 242 that is configured to abut the horizontalsurface. The plate 240 may define an upper face 244. The plate 240 maybe circular.

The plate 240 (e.g., the upper face 244) may define a first portion 244A(e.g., a first upper surface) and a second portion 244B (e.g., a secondupper surface). The first portion 244A may be defined between a centerof the plate 240 and a first radius R1 from the center of the plate 240.The second portion 244B may be defined between the first radius R1 and asecond radius R2 from the center of the plate 240. The first portion244A and the second portion 244B may define a cavity 246. For example, adifference between the first portion 244A and the second portion 244Bmay define the cavity 246. The cavity 246 may be configured to receive aportion of the remote control device 200. The remote control device 200(e.g., the rear surface 214 of the base 210) may abut the first portion244A when received by the cavity 246.

Alternatively, the plate 240 (e.g., the upper face 244) may define afirst thickness at the first radius R1 from the center of the plate 240.The plate 240 may define a second thickness between the first radius R1and the second radius R2 from the center of the plate 240. The secondthickness may be greater than the first thickness. A difference betweenthe first thickness and the second thickness may define the cavity 246.The cavity 246 may be configured to receive a portion of the remotecontrol device 200. Stated differently, the first portion 244A (e.g.,the first upper surface) may define the first thickness and the secondportion 244B (e.g., the second upper surface) may define the secondthickness.

The platform 250 may extend from the plate 240 (e.g., the upper face244). For example, the platform 250 may extend from the first portion244A of the upper face 244. A midpoint of the platform 250 may belocated slightly offset from the center of the plate 240. For example,the platform 250 may be offset from the center of the plate 240 suchthat the remote control device 200 is centered on the plate 240 whensecured to the pedestal 230. The platform 250 may include an aperture252.

The mounting tab 260 may extend from the platform 250. The mounting tab260 may extend into the opening 212 defined by the base 210. Themounting tab 260 may be configured to prevent rotation of the remotecontrol device 200 (e.g., the base 210) when the base 210 is attached tothe pedestal 230. For example, the mounting tab 260 may be configured toprevent rotation of the base 210 when the rotating portion 222 isrotated. The remote control device 200 may include a fastener 270. Thefastener 270 may be configured to secure the remote control device 200to the pedestal 230. For example, the fastener 270 may be configured tosecure the base 210 to the platform 250. The aperture 252 may receivethe fastener 270, for example, to secure the remote control device 200(e.g., the base 210) to the pedestal 230. The fastener 270 may beself-threading. For example, the aperture 252 may be sized such that thefastener 270 secures the base 210 to the platform 250. Alternatively,the aperture 252 may be threaded such that the aperture 252 hascomplimentary threads to those of the fastener 270. The base 210 maydefine a through-hole 215 that is configured to receive the fastener270.

FIGS. 6-8 illustrate another example remote control device 300 having apedestal 330 (e.g., such as the remote control device 200). The pedestal330 may be configured to be attached to the remote control device 300.The remote control device 300 may be deployed as the tabletop remotecontrol device 116 in the load control system 100 (e.g., as shown inFIG. 1 ). The remote control device 300 may be configured to control theamount of power delivered to, and thus the intensity of, at least onelighting load. The remote control device 300 may include a base 310 anda control unit 320 that may be attached to the base 310. The base 310may alternatively be referred to as a base portion or a mountingassembly. The control unit 320 may alternatively be referred to as acontrol module. It should be appreciated that other control unitsdescribed herein may similarly be alternatively referred to as controlmodules. The control unit 320 may include a rotating portion 322 that isrotatable with respect to the base 310 (e.g., an annular rotatingportion that is configured to rotate about the base). The control unit320 may include an actuation portion 324, which may be operatedseparately from or in concert with the rotating portion 322. The remotecontrol device 300 may be configured such that the control unit 320 andthe base 310 are removably attachable to one another.

The pedestal 330 may be a mount that is configured to rest on ahorizontal surface. The pedestal 330 may be configured to receive thecontrol unit 320. For example, the base 310 may be mounted to thepedestal 330. The pedestal 330 may include a bottom plate 336, a topplate 340, a platform 350, and a mounting tab (e.g., such as mountingtab 260 shown in FIGS. 4 and 5 ). The bottom plate 336 may be circular.The bottom plate 336 may be attached to the top plate 340. For example,the pedestal 330 may include a weight 370. The weight 370 may beconfigured to increase the mass of the pedestal 330 and/or increase thetorque resistance of the pedestal 330. The bottom plate 336 may surrounda portion of the weight 370. The bottom plate 336 may be attached (e.g.,using adhesive) to the weight 370. The weight 370 may be attached to thetop plate 340. The weight 370 may be hidden from view by the top plate340 and the bottom plate 336.

The bottom plate 336 may be configured to rest on a horizontal surface.The bottom plate 336 may be rubber, synthetic rubber, silicone, and/orthe like. For example, the bottom plate 336 may define a bottom surface338 that is configured to abut the horizontal surface. The bottomsurface 338 may be concave. For example, the bottom surface 338 mayinclude a recessed portion 302 and a flat portion 304. The flat portion304 may be proximate to (e.g., along) an outer perimeter of the bottomplate 336. The flat portion 304 may be configured to rest on thehorizontal surface. The recessed portion 302 may be spaced from thehorizontal surface, for example, when the flat portion 304 rests on thehorizontal surface. The recessed portion 302 may extend a distance D1from the flat portion 304 (e.g., as shown in FIG. 8 ). The distance D1may be at least 0.01 inches. The recessed portion 302 may beconcave-shaped (e.g., as shown in FIG. 6 ).

The flat portion 304 may be configured to resist movement of the remotecontrol device 300 with respect to the horizontal surface on which thebottom plate 336 (e.g., the flat portion) rests. The flat portion 304may extend from the outer perimeter of the bottom plate 336 (e.g., outeredge 306) to a predetermined radius (e.g., radius R3 as shown in FIG. 7) from a center of the bottom plate 336. The outer perimeter of thebottom plate 336 may be defined by a radius R4. The predetermined radiusR3 may be determined such that a surface area of bottom plate 336contacting the horizontal surface is minimized while satisfying africtional force threshold. For example, the frictional force that thebottom surface 338 can resist may be based on the predetermined radiusR3. The predetermined radius R3 may be configured such that the pedestal330 is configured to prevent movement of the pedestal 330 (e.g., withrespect to the horizontal surface) when a torque is applied parallel tothe flat portion 304. The bottom plate 336 may be configured such that africtional surface area (e.g., the flat portion 304) has a larger outerdiameter (e.g., diameter D3) than an outer diameter (e.g., diameter D2)of the rotary knob 320 of the control unit 320.

The top plate 340 may define an upper face 330. The top plate 340 may becircular. The top plate 340 (e.g., the upper face 344) may define afirst portion 344A (e.g., a first upper surface) and a second portion344B (e.g., a second upper surface). The first portion 344A and thesecond portion 344B may define a cavity 346. For example, a differencebetween the first portion 344A and the second portion 344B may definethe cavity 346. The cavity 346 may be configured to receive a portion ofthe remote control device 300. The remote control device 300 (e.g., therear surface 314 of the base 310) may abut the first portion 344A, whenthe remote control device 300 is received by the cavity 346.

The platform 350 may extend from the top plate 340 (e.g., the upper face344). For example, the platform 350 may extend from the first portion344A of the upper face 344. The platform 350 may be configured toprevent rotation of the remote control device 300 (e.g., the base 310)when the rotating portion 322 is rotated. The remote control device 300may include a fastener (e.g., the fastener 270) that is configured tosecure the base 310 to the pedestal 330.

FIGS. 9-11 illustrate another example remote control device 400 having apedestal 430 (e.g., such as the remote control device 200).

It should be appreciated that other control unitsdescribed herein may similarly be alternatively referred to as controlmodules. The control unit 420 may include a rotating portion 422 that isrotatable with respect to the base 410 (e.g., an annular rotatingportion that is configured to rotate about the base). The control unit420 may include an actuation portion 424, which may be operatedseparately from or in concert with the rotating portion 422. The remotecontrol device 400 may be configured such that the control unit 420 andthe base 410 are removably attachable to one another.

The pedestal 430 may be a mount that is configured to rest on ahorizontal surface. The pedestal 430 may be configured to receive thecontrol unit 420. For example, the base 410 may be mounted to thepedestal 430. The pedestal 430 may include a bottom plate 436, a topplate 440, a platform 450, and a mounting tab (e.g., such as mountingtab 260 shown in FIGS. 4 and 5 ). The bottom plate 436 may be circular.The bottom plate 436 may be attached to the top plate 440. For example,the pedestal 430 may include a weight 470. The weight 470 may beconfigured to increase the mass of the pedestal 430 and/or increase thetorque resistance of the pedestal 430. The bottom plate 436 may surrounda portion of the weight 470. The bottom plate 436 may be attached (e.g.,using adhesive) to the weight 470. The weight 470 may be attached to thetop plate 440. The weight 470 may be hidden from view by the top plate440 and the bottom plate 436.

The bottom plate 436 may be configured to rest on a horizontal surface.The bottom plate 436 may be rubber, synthetic rubber, silicone, and/orthe like. For example, the bottom plate 436 may define a bottom surface438 that is configured to abut the horizontal surface. The bottomsurface 438 may be concave. For example, the bottom surface 438 mayinclude a recessed portion 402 and a flat portion 404. The flat portion404 may be proximate to (e.g., along) an outer perimeter of the bottomplate 436. The flat portion 404 may be configured to rest on thehorizontal surface.
